Assassin's Creed Valhalla käsittelee teemanaan viikinkejä, eikä Ubisoft epäröi ottaa vapauksia historiallisen tarkkuuden kanssa. PC Games N:lle puhunut peliohjaaja Eric Baptizat paljasti, että myös Asgardissa ja Jotunheimissa päästään käymään.
"An interesting [result] of that is the line between myth and reality is blurred - everything that happened to people was explained as being sent from the gods. So we play a lot with this, and you'll see many elements [of life] as they correlate to Norse mythology.
"Take Valka, the seer. She is a kind of shaman, and when you build a hut for her in your settlement, she allows you to go on a vision quest in which you'll visit some of the worlds of Norse mythology. So you can access Asgard and Jotunheim."
